Variations include Breakout and Arkanoid like games, "Arcade hits" (original games or bootleg ones), I Spy rip off games (there all alike but with diffrent images so might as well be just one huge game), card games, a hole slew of puzzle bobble and zuma ripp off games, time management, match 3 bejewled/candy crush ripp off games, sport game and puzzle games. From a 3d ball platformer (the most original game so far) to a straight up rip-off of DrMario called "Docter's Lab". You can get these games from walmart for $15.00 the same price is able to get the 500,000 in 1. It's shameful but only worth it for the very few games that is not ripping off of a popular game or adding to the big pile of bejewled rippof games. soon is a vertion that contans all of the games preinstalled in just 1 zip file! all you have to do with that zip file is find the game to install then click and drag to where ever you want to install them in.
